Subject: [PATCH 1/2] mtd: spi-nor: locking support for MX25L6405D
|
||
|
|
|
||
|
|
Macronix MX25L6405D supports locking with four block-protection bits.
|
||
|
|
Currently, the driver only sets three bits. If the bootloader does not
|
||
|
|
sustain the flash chip in an unlocked state, the flash might be
|
||
|
|
non-writeable. Add the corresponding flag to enable locking support with
|
||
|
|
four bits in the status register.
|
||
|
|
|
||
|
|
Tested on Nanostation M2 XM.
|
||
|
|
|
||
|
|
Similar to commit 7ea40b54e83b ("mtd: spi-nor: enable locking support for
|
||
|
|
MX25L12805D")
